NFD - Flat fan spray nozzle

NFD flat fan nozzle is used when there is a need for high precision alignment of the spray. The spray tip can easily be replaced, which makes it easy to adjust the flow rate if necessary.

Connection availble as thread or for welding.

NF flatstråledysa har en spraytipp som enkelt kan bytas ut, vilket gör det möjligt att justera flödet. Spraytippen går också att rikta in för att ge bättre precision i sprayen.

Design features

  • Used when there are high requirements for precision in the alignment of the spray.
  • The spray tip can easily be replaced, making it possible to adjust the flow rate if necessary.
  • The spray tapers slightly towards the outer edges, which makes the nozzle very suitable for applications where several nozzles are installed in line. By overlapping the spray of the nozzles, the result is an even spray across the entire line.

Flow rates, spray angles & connections

If a specific pressure is not listed below or in the nozzle datasheet, it is possible to calculate the nozzle flow rate at a given pressure by using the equation at the bottom of the datasheet.

Choose the right spray nozzle for an optimised spray process

Each type of nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and type of solution.

The Knowledge base contains information about spray pattern, droplet size, flow rate/pressure, spray coverage, materials, etc. The 'Materials' section of the Knowledge base lists the most commonly requested materials and maximum temperature of the material.

Our main supplier is BETE, a leading manufacturer of spray nozzles and spray systems with more than 70 years of experience in spray processes and a product range including over 20,000 components.

BETE's spray technology is used worldwide to optimise processes in many different industries, including the energy sector, chemical and petrochemical industry, food industry and offshore.

Some of BETE's certifications include ISO 9001:2015, ATEX and FM Approval.
